The film has always been excellent. The problem is that Fuji is ending processing by Fuji, and one is tuck with the substandard (poor) procesing of Fujichrome film by assorted mail-order outfits. I have tried a number of such outfits that advertise in the back pages of photo magazines and they are pretty poor by comparison to processing by Fuji using mailers. End of an era.
This film is absolutely stunning, but can be challenging to shoot. When you nail it, nothing looks better than Velvia 50. Make sure you overexpose slightly in lower light and follow the manufacturer directions for exposure. There is very little room for error, so make sure you know what you're doing before you shoot a bunch of this expensive color reversal film. I had success shooting this handheld, particularly with wider lenses and lenses with IS, but use a monopod if you are uncertain of the light.
The colors on this film are fantastic, and it's got a very smooth, subtle grain as well. Be careful using it though, as it's not a C-41 film, so some labs may end up cross-processing it which will distort the color in your photos significantly. It's ISO 50, so pretty much only useable in bright sunlight outdoors, or with a strong flash setup.
